Description
Technical field
The present invention relates to doctor blade system (doctor bladesystem) according to claim 1 preamble.The invention further relates to doctor blade clamping device according to claim 12 preamble.The present invention also further relates to according to the doctor blade system in the band chamber of claim 22 preamble (chambered doctor blade system).The invention still further relates to printing element according to claim 23 preamble.The present invention relate at last according to claim 24 preamble be used to clamp the method for scraper and according to the method for the scraper clamping part that is used for the sclerozone chamber of claim 28 preamble.
Background technology
Scraper such as the scraper in band chamber is widely used for particularly being used in the flexographic printing unit in the rotary printing element, is used for China ink, lacquer, adhesive etc. are supplied to the rotatable tube that is included in the printing element.For example, in the flexible printing unit, the scraper in band chamber is used to screen roller (screen roller) ink supply.This realizes by by means of the scraper in band chamber the compartment of roller or recess being filled with China ink.The scraper in this kind band chamber is for example open in WO 93/24328.The scraper in the band chamber of this type comprises long and narrow framework, and described framework has two long and narrow scrapers, is provided with in the following manner along roller: the longitudinal axis of the scraper in band chamber limits a long and narrow chamber, and described long and narrow chamber for example keeps China ink.When being applied to China ink etc. on the roller periphery, the scraper in band chamber also is applied to it.The function of each scraper changes with the roller direction of rotation is different.A scraper (wiping scraper) is wiped too much ink off, and another scraper only has sealing function.
The ink supply of screen roller is vital to printing effect.Particularly importantly, screen roller is even ink supply, this means that the distance between roller and the scraper must accurately be provided with.As a result, the scraper that is clamped in the band chamber in the printing element frame usually must present good bending and warping rigidity.
Therefore the scraper in the band chamber of prior art comprises firm framework, and it is normally solid and make single-piece, and scraper is mounted thereto.EP-A-0 350 839 and WO-A-89/07047 for example teaching the scraper in band chamber of this type.
Usually, this kind scraper is to be made by solid cast or aluminium, perhaps makes to reduce weight by having compression molded iron or the aluminium blank of strengthening spring.Yet these known structures have some important disadvantages.At first, the scraper in band chamber becomes very heavy and is difficult to use, thus be difficult to pull down from printing element, for example, when needs clean or replace.Usually need two people to pull down the scraper in the band chamber of cast iron.The second, all need a cover casting die for each length of scraper in band chamber.The 3rd, the cast iron structure is corrosion easily naturally, and this causes serious inconvenience, because the printing ink that circulates in described chamber contains the composition that is corrosive usually.
The doctor blade frames that also provides the multi-section of making by extruded aluminium to be divided into single-piece on the market, but these can not provide any gratifying solution to the problems referred to above.If for the stress that stands to expect and obtain sufficient bending and transverse strength, described aluminum portions must be quite thick and the scraper band chamber the recuperation that will become surpass needs.In addition, aluminum portions is corrosion easily also, because printing ink contains usually aluminium is had rodent base substance.
Outside the requirement of Tao Luning, inking chamber naturally must sealing in front.The scraper of removing excess ink in the anticipated orientation of roller rotation is the scraper of operation, and another scraper only has sealing function.When direction of rotation changed, it was worked naturally in another way.Described two scrapers must be applied to the periphery against screen roller, make China ink be evenly distributed on the roller with accurate way, and make the quantity of ink that drips from lower coating blade (when being seal blades) minimize.In addition, in this regard, need special sealing in the each end in described chamber.With reference to US-A-4,581,995, its teaching be arranged on the sealing unit at inking chamber end place, the sealing unit comprises pressure and the labyrinth seal that the thin sealing thin layer by several polymeric materials constitutes.
US-A-5,671,673 teachings a kind of scraper equipment with the chamber, wherein the framework for the scraper that obtains good reinforcement and strengthening effect band chamber is made of interconnective metal part subassembly.The described framework that partly is made of metal should form a bending and the high rigid element of transverse strength, guarantee described framework and and scraper will against cylindrical shell between the contact distance.For this kind design of framework, the scraper in entire belt chamber can have better and more very thin structure, and can not reduce strength criterion.
According to US-A-5,671,673, the scraper equipment that has the band chamber of internal chamber has bar, bar-cutter retainer or single scraper, passage and the exterior chamber of clamping, the scraper equipment in described band chamber has too many parts, unnecessary inking surface and the corner that has the capillary slit, described corner are difficult to get at the effective cleaning to carry out simple in printing element.
A common problem of prior art doctor blade system is, scraper and scraper against cylindrical shell wear and tear apace, this is expensive, and causes often changing scraper and cylindrical shell, and carries out clean operation continually.
Another problem that occurs in doctor blade system is that when scraper clamped partial rupture, whole doctor blade system must substitute or sent for maintenance.
Summary of the invention
One object of the present invention is to provide a kind of doctor blade system, although this kind doctor blade system is in light weight, has enough bendings and warping rigidity and guarantees rotary barrel quilt cover cap equably, makes scraper contact with described cylindrical shell equably.
Another object of the present invention is to provide the doctor blade system of a kind of easy cleaning and maintenance.
A further object of the present invention is to provide a kind of doctor blade system, and wherein the stress on the cell of stress on the scraper and rotary barrel and the little locular wall reduces.
Of the present invention again again a purpose be to provide a kind of doctor blade system, it is beneficial to simply, safety and change scraper apace and end sealing that printing machine is inside and outside.
Of the present invention again again a purpose be to provide a kind of doctor blade system, it is beneficial to simply, change China ink apace, and need not described chamber is taken off from printing machine.
Another purpose again of the present invention is to provide a kind of doctor blade system of the band chamber that can quite easily keep in repair.
Be appreciated that by following description, these and other objects realize by a kind of doctor blade system, this doctor blade system is as stated type that Introductory part is introduced, and has the technical characterictic of being put down in writing in claim 1,12,22,23,24 and 28 characteristics in addition.The preferred implementation of doctor blade system of the present invention and method limits in dependent claims 2-11,13-21 and 25-27.
The advantage that this system provides is: the whole length along scraper keeps scraper with very uniform clamping force, thereby if opening is straight, scraper keeps with the clamping straight and plane, and this causes scraper to contact roller equably again.
Another advantage is: since scraper when clamping whole or in part by at least one elastomeric elements or corresponding construction around, so be cushioned owing to the cell that forms in the roller influences stress and the vibration that described scraper produces, particularly be suppressed by oppositely striking off, a purpose is the impact that suppresses from the wall/bar between the described cell (bar).The wearing and tearing that this has reduced scraper and roller cell and little locular wall make them wear and tear slowlyer, and the result prolongs their service life.This is a particular importance for the scraper in the intaglio printing, roughly covers chromium-copper spare by the band engraving cell of easy wearing and tearing at roller surfaces in such cases and constitutes.In other application such as flexographic presses, the ceramic coating of laser engraving provides the surface of screen roller, thereby, mainly be the wearing and tearing that reduce scraper.
An advantage more of the present invention is: have the elastomeric elements that a part forms spline by use, scraper remove and replacing become extremely easily with fast.In addition, to doctor blade system clean be simple with effectively because be not difficult to the corner of the band capillary slit that gets at basically.
The advantage of lubricating spline with suitable lubricant is, if described lubricant makes scraper be pushed down easily against described opening the bottom---scraper does not also get there.
The advantage that the simplification embodiment of clamping scraper is provided is, scraper just partly by elastomeric ring around, described simple application makes even can remove scraper more simply, and make to get at easily and clean, although but also have inhibition---this inhibition is limited, and described inhibition provides against elastomeric elements by the scraper protuberance.Simultaneously described scraper is caused the compensation that adds against the contact of mentioned roller against the protuberance of elastomeric elements.
Use elastomeric elements that the advantage that the apparatus for fastening that separates is applied to described framework and provides is, can only change or keep in repair apparatus for fastening (if damaged) in fixing providing firm.This has reduced cost.
